FMS 1300mm PA-18 3536 Motor Shaft For 1400mm Kingfisher, 1300mm PA-18, 1020mm F3A
Description
The DolphinRC Lark X7 is a 7-inch deadcat-style (DC) FPV frame kit built for long-range cruising and high-definition cinematic flying. A 322mm wheelbase carbon fiber chassis with aerospace-grade aluminum alloy hardware keeps the airframe rigid yet light at just 388g, leaving plenty of payload headroom for a GoPro-class action camera and a 6S long-range battery. From assembly and tuning to real-world flying, the Lark X7 is designed to make the whole process straightforward for both seasoned builders and pilots stepping up to their first 7-inch rig.
Key Features
✅ Carbon Fiber + Aerospace Aluminum Structure — High-strength carbon plates paired with aluminum alloy standoffs and camera cage deliver a stiff, crash-resistant airframe that stays stable in high-speed flight and gusty conditions.
✅ Quick-Release 6mm Arms — Thick 6mm arms with a tool-friendly quick-release design let you swap a damaged arm in minutes instead of rebuilding the whole quad.
✅ Integrated Audio-Visual Alert System — Dual high-decibel buzzers help you locate a downed quad fast, while the built-in RGB Bluetooth lighting module is fully configurable through a smartphone app for different scenes and visibility needs.
✅ Adjustable HD Camera Mount with Full Alloy Protection — The 20mm camera mount offers adjustable tilt front and rear, wrapped in an all-around aluminum alloy cage that shields your HD camera in hard landings.
✅ Anti-Interference Antenna & GPS Mounting — A dual-mount layout for the receiver antenna and GPS physically isolates them from strong magnetic sources, improving positioning accuracy on long-range flights.
✅ Builder-Friendly Electronics Bay — Modular split side panels, an external parameter tuning port (adjust settings without opening the frame), and standard 30.5mm stack / 25.5mm + 30.5mm VTX mounting make it compatible with the vast majority of mainstream electronics.

FAQ
Q: What propeller and motor sizes does the Lark X7 support?
A: It is designed for 7–7.5 inch propellers with 2806 or 2808 size motors (19mm / Ø3mm mounting pattern, 4 holes).
Q: Does the frame kit include motors, a flight controller or a camera?
A: No. The package contains the frame and its mounting hardware only — all electronics, propellers and battery are purchased separately, so you can choose the exact setup you prefer.
Q: What battery should I use for long-range flights?
A: DolphinRC recommends a 6S 3500mAh LiPo for general flying, or a 6000mAh Li-ion pack for maximum long-range endurance.
Q: Can I adjust flight controller settings without opening the frame?
A: Yes. The Lark X7 has an external parameter tuning port, so you can plug in and tune without disassembling the airframe.
Q: Is there an upgrade path to a larger frame?
A: A 10-inch variant is planned — according to DolphinRC it can be converted by swapping only the arms and motors, keeping your existing frame and electronics investment.
Note: Package contents cover the frame kit and its assembly hardware only. Electronics and accessories shown in build photos are for illustration and are not included.
